The article demonstrates the importance of using StringComparison options for efficient string comparison in.NET. How you compare strings can significantly impact your application performance. The ToLower method creates a new string memory allocation for each comparison, leading to unnecessary allocations. The OrdinalIgnoreCase option is ideal for case-insensitive comparisons where cultural rules do not apply.

Heap allocations aren’t entirely bad but when an object is allocated on a heap it contributes to the garbage collection cycles which in turn reduces overall application performance. In case of excessive heap allocation, the garbage collector can lead to GC pauses. One approach to optimize resource usage in async code is by using ValueTask syntax.
